4 Claims. (01. 103-90) The present invention relates to new and usefulimprovements in pumps and more particularly to a turbine pump for' usein pumping water from wells.

An important object of the invention is to provide a turbine pumpincluding a rotary shaft having a plurality of impellers at suitablyspaced apart intervals and providing a novel bearing construction forcentering-the shaft in a well casing.

Another object of the invention is to provide novel means for lockingthe bearing against rotation in the well casing.

A still further object is to provide a device of this character ofsimple and practical construction, which is efficient and reliable inoperation, relatively inexpensive to manufacture and otherwise welladapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which.

Figure 1 is a vertical sectional view of the assembled pump;

Figure 2 is an enlarged fragmentary vertical sectional view takensubstantially on the line 2-2 of Figure 1, and;

Figures 3 and 4 are transverse sectional views taken respectively on thelines 3-3 and 44 of Figure 2.

Referring now to the drawings in detail wherein for the purpose ofillustration I have disclosed a preferred embodiment of this inventionthe numeral 5 designates a casing in which a rotary shaft 6 ispositioned, the casing having a water outlet head I attached to itsupper end and formed in its side with outlet openings 8. The upper endof shaft '6 is journaled in a bearing 9 at the top of the head 1 and apulley I is attached to the upper end of the shaft and is driven by abelt I I from a motor or other suitable power source I2.

A plurality of impellers I 3 are secured to shaft 6 by set screws It forlifting water entering the bottom of the casing to the head I anddischarged through the openings 8.

A plurality of bearings designated generally at I are positioned in thecasing between the impellers I3 and a collar I6 secured to the shaftabove each of the bearings by set screws IT.

The bearings I5 comprise a rubber bearing sleeve I8 enclosed in a metalsleeve I9 and from which a plurality of centering fins project radiallyfor. engaging 2 the casing and the bearing in the casing. I

The bearing is locked against rotation in, the casing by a locking fin2| swingably mounted on a vertical pin 22 secured in upper and lowereyes 23 and 2t and one side of metal sleeve I9, the fin 2|beingswingable circumferentially of the casing 5 into wedgingengagementtherewith. A coil spring 25 is positionedon pin 22 with one; end 326 ofthe spring bearing against. the metal sleeve"!!! of the bearing and theother end 21 of the spring bearing against one side of locking fin 2| toforce the latter into wedging locking engagement with the inner surfaceof the casing.

In the operation of the device the shaft 8 is rotated by the motor I2and the impellers I3 are thus driven to lift the water in the casing tothe discharge head I.

The bearings I5 are positioned on the shaft immediately adjacent theimpellers to center the impellers in the casing and to prevent vibrationof the shaft.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the sprit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. In a turbine pump, the combination with a well casing having a rotaryshaft therein with an impeller secured to the shaft within the casing,of a bearing in the casing in which the shaft is journaled including arigid sleeve, rigid radial fins on the sleeve engaging the casing andcentering the sleeve in the casing, a locking fin in the casing pivotedto the sleeve and swingable into wedging engagement with the casing tohold the sleeve and radial fins stationary in the casing, and a torsionspring mounted on the locking fin and reacting against said sleeve andlocking fin to swing said locking fin into engagement with the casing.

2. In a turbine pump, the combination with a well casing having a rotaryshaft therein with an impeller secured to the shaft within the easing,of a bearing in the casing in which the shaft centering is journaledincluding a rubber bearing sleeve, a rigid sleeve telescoped over therubber sleeve, radial rigid members on the rigid sleeve engaging thecasing and centering the sleeve in the casing, a locking member in thecasing pivoted on the rigid sleeve and swingable about an axis parallelto the axis of the rigid sleeve into engagement with the casing to holdthe rigid sleeve and rigid members stationary in the easing, and atorsion spring mounted on the locking member and reacting against therigid sleeve and locking member to swing said locking member intoengagement with said casing.

3. In a turbine pump, the combination with a well casing having a rotaryshaft therein with an impeller secured to the shaft within the easing,of a bearing in the casing in which the shaft is journaled including arigid sleeve, rigid radial fins on the sleeve engaging the casing andcentering said sleeve in the casing, and a locking fin in the casingpivoted on the sleeve and swingable circumferentially of the easing intoWedging engagement with the casing to hold the sleeve andradial finsstationary in the casing.

4. In a turbine pump, the combination with a well casing having a rotaryshaft therein with an impeller secured to the shaft within the easing,of a bearing in the casing in which the shaft is journaled including arigid sleeve, rigid means fixed to and spaced around said sleeve andengaging the casing to center the sleeve in the casing, a fin extendingparallel with the axis of the sleeve and pivoted thereto and swingablecircumferentially of the easing into wedging engagement therewith tohold the sleeve and said rigid means stationary in the casing, and atorsion spring mounted on said fin and reacting against said sleeve andfin to swing said fin into engagement with the casing.
